Title: Improvements in or relating to the hydrogenation of cresols and other phenolic compounds
Filed: 1934-03-13
Abstract: In the conversion of cresols and other phenolic compounds into hydrocarbons by catalytic treatment with hydrogen, use is made of a catalyst consisting of or containing a metallic thiomolybdate, e.g. a thiomolybdate of cobalt, chromium, tin or bismuth.  Such thiomolybdates may be prepared by treating a soluble salt of the metal with ammonium thiomolybdate in aqueous solution.  The reaction may be effected at 400--600 DEG  C. and atmospheric or raised pressure.  Gases containing hydrogen, e.g. coke-oven gas or town gas, and commercial mixtures containing cresols or other phenolic compounds, may be used.  The catalyst may be supported on pumice or other porous carrier.  The use of thiomolybdates containing a volatile cation, and of other thiomolybdates which are converted into sulphides at the reaction temperature, is disclaimed.  An example is given in which commercial cresol and hydrogen are passed at 425--450 DEG  C. over cobalt thiomolybdate mounted on a porous support; toluene is the main product.ALSO:As catalysts for the conversion of cresols and other phenolic compounds into hydrocarbons by treatment with hydrogen, use in made of metallic thiomolybdates, e.g. a thiomolybdate of cobalt, chromium, tin or bismuth.

Title: Improvements in or relating to Wire-stitching Machines and the like.
Inventor: WADE HAROLD
IPC: B31B3/60
Filed: 1918-05-13
Abstract: 120,002. Wade, H., (Boston Wire Stitcher Co.). May 13, 1918. Stapling and discontinuous wire-stitching.-A work-guide for use in stapling or wire-stitching machines for securing together the flaps or sides of collapsible cartons or similar articles comprises a bottom plate D formed with clinching cavities d and having secured to it by screws s a cleat or side-rest E, to which is riveted, so as to be flush with its upper surface, a top plate F. Coincident with the end of the cleat, the rear portion of the plate F is bent upwards at a slight angle, Fig. 3, while the rear end of the plate is upturned at right-angles to form a flange f, which is secured by screws v to the head of the machine, with the bottom plate D spaced from the usual horizontal table T. About half-way across its width, the forward end of the plate F is bent upwards to form a lip f<2> while at the rear of the cleat E the plate is slit at f<3>, f<4> and upturned to form an apron f<5>. The carton blank C comprises four flaps c, c<1>, c<2>, c<3>, the blank being scored, at for bending the flap c<2> at right-angles to the flap c<1>, and at x<1> to adapt it to be folded at this point to provide a narrow strip c' by which the flaps c, c<3> are connected together. The blank is placed in the machine with the flaps c<1>, c<2> resting on the table T, and with the flaps c, c<3> bent upwards at x<3>, x<4>, the, folded edge x<4> being positioned against an adjustable gauge H. As the blank is pushed. forwards, the flap c is folded over the cleat E to position its marginal edge over the strip c<4>, and as the blank meets the edge of the top plate F, the flap c passes on to the upper side of the top plate while the lip f<2> deflects the flap c<3> so that it is fed along the bottom plate D. As the blank is fed still further, the leading edge of the flap c slides under the apron f<5> so that it rests on the strip c<4>, to which it is then secured on the operation of the stapling-mechanism. The staples are clinched against the plate D, which is sprung down and clamped against the table T to hold the blank against movement during the driving of the staple, and which also prevents the stitching from -engaging the flap c<1>. In a modified construction, the plates D, F are made in one piece from sheet metal.

Title: A Mathematical Instrument for the Trisection of a Plane Rectilineal Angle.
Inventor: HODGINS RICHARD
Filed: 1916-06-07
Abstract: 104,282. Hodgins, R. June 7, 1916. Dividing-instruments.-An instrument for trisecting angles comprises two bars C P, B P free at their ends but pivoted at O and Q to a bar OQ so that O Q = Q P = 0 'B. To trisect an angle- B A C, a circle is drawn through the apex A with centre O so that the radius O A = O Q. Let this circle cut the lines B A, C A respectively at points B, C. The instrument is then placed so that the pivot 0 coincides with the centre of the circle, with the bar B P falling upon the line B A, and with the bar C P passing through the point C. Still observing these conditions, the pivot Q is then moved round the circle until the end P of the bar C P touches the bars B P. The pivot Q will then assume the position shown in the Figure, so that the arc A Q is 1/3 the arc B C. Arcs B D, D E are then cut off equal to arc A Q. Then the lines D A, E A trisect the angle B A C. The Specification contains a mathematical demonstration.

Title: Improvements in or relating to the production of organic halogen compounds
Inventor: ROBERTSON MYLES JAMES
IPC: C08F8/20
Filed: 1941-06-27
Abstract: In the manufacture of chlorinated polymers of ethylene by chlorinating polyethylene suspended, dispersed or dissolved in an inert liquid medium, part of the chlorination is carried out at a temperature below 45 DEG  C., e.g. at 15 DEG  to 40 DEG  C., and another part at a temperature between 55 DEG  and 150 DEG  C., e.g. between 60 DEG  and 90 DEG  C.  The inert liquid medium may be one which dissolves polyethylene or the partially chlorinated product, e.g. carbon tetrachloride, or may be one which causes the polyethylene or the partially chlorinated product to swell without dissolving, e.g. trichloracetic acid, or one which has action on the polyethylene or the partially chlorinated product, e.g. water.  The process may be assisted by light irradiation, and may be carried out in batches or continuously.  The products are soluble in carbon tetrachloride, benzene, toluene, tetrahydronaphthalene, trichlorethylene ketones and esters, and may be used as paints, lacquers or dopes and for making sheets, tubes, films, fibres and mouldings.  Specifications 481,515 and 519,422 are referred to. According to the Provisional Specification, polyethylene is halogenated by treatment in the presence of a dispersing medium with one or more halogens or a substance capable of introducing halogen, and when some halogen has been introduced into the polymer, the temperature is changed and the halogenation is continued to the desired extent.

Title: Mechanical doll
IPC: A63H13/04
Filed: 1972-02-23
Abstract: 1338737 Converting rotary motion to reciprocating motion; positive clutches A E GOLDFARB 23 Feb 1972 [24 Feb 1971] 8345/72 Headings F2C and F2Q [Also in Division A6] A mechanical, motor-driven doll (see Divisions A5-A6) has its upper torso rocked back-and forth, and from side-to-side. Convertinq rotary motion to reciprocatinq motion.-In one form, a motor driven gear 37, Fig. 1, carries pivotally and eccentrically one end of a rod 41 journalled by a ball 45 in a fixed frame 49 so that its top end 51 performs an orbital movement. A second frame 61, mounted for pivotal motion both from side-to-side and back-and-forth of the doll, carries two disks 57, 59, (see also Fig. 4c), having diametral slots 69, 71 through which the top end of the rod 51 passes. The two disks 57, 59 are angularly adjustable and interconnected within the second frame 61 for manual control. In one extreme position, the two slots 69, 71 are aligned parallel to the shoulders of the doll. Accordingly the upper end 51 of the rod slides along the slots 69, 71 and only the fore-and-aft component of the orbital motion of the rod is effective, to move the disks, &c. 57, 59 back-and-forth, so that the doll nods forwards, &c. By turning the two disks 57, 59 through 90 degrees, the slots 69, 71 are aligned perpendicularly to the shoulders; accordingly the rod end 51 slides in the slots in the back-and-forth direction, and the frame 61, &c. rocks from side-to-side. Further angular adjustment of the lower disk 59 is prevented by abutment of a lug on the disk with a lip on the frame 61. However, the upper disk 57 can be turned through a fastener 90 degrees, overcoming the connection between the two disks, to the position shown, Fig. 4c, with the two slots 69, 71 at right angles. The frame 61 is thus constrained to follow the back-and-forth, &c. motions of the rod end 51, and perform a rotating movement. Adjustment of the angular settings of the disks 57, 59 between the described positions provides compound movements. Positive clutches.-In another form, two positive clutches having two output members 149, 151, Fig. 8, journalled upon a rod 143 and actuating separate mechanisms, has a driving clutch member 141 slidden to three operative positions. In the first position, the driven clutch member 149 is engaged, as shown. By sliding the driving clutch member 141 rightwards to a second, median, position, the second driven clutch member 151 is also engaged, without disengagement from the first driven clutch member 149, Fig. 10c (not shown). When the driving clutch member 141 is slidden to a third, extreme right position, the driven clutch member 149 is disengaged.

Title: Improvements in or relating to electrical indicating and remote-control apparatus
IPC: G08C19/02
Filed: 1941-07-04
Abstract: 550,426. Regulating switches. MIRZA, R. N., and ALLEN,F. J. July 4, 1941, No. 8495. [Class 38 (v)] [Also in Group XXXVI] In indicating or remote control apparatus in which a potentiometer is tapped by two or more adjustable contacts connected to a receiver of the synchronous motor type, the potentiometer is so constructed as to give a sinusoidal variation of potential for uniform movement of the contacts. In the construction shown in Fig. 1, resistance wire 12 is wound on a cylindrical former having one end 10 normal to the axis and the other end 11 shaped sinusoidally between the two ends of a diameter. A battery 13 is connected across diametrically opposite points 16, 17. Three moving contacts 20 are carried by arms 19 spaced 120 degrees apart on a spindle 18 and are connected to slip-rings 21 which are engaged by brushes 22 for connection to a three-phase receiver. Other numbers of contracts may be employed for use with receivers of other numbers of phases. In a modification, Fig. 2, a spindle 24 carries contact arms 25 engaging a circle of contacts 26. The resistance wire 27 is uniformly wound on a cylindrical or other former of a length equal to the diameter of the circle of contacts 26. Each contact is connected by a wire 28, at right angles to the axis of the former, to a point on the winding. Each contact is therefore projected on to a diameter of the circle of contacts and the potential of any contact is proportional to the cosine of the angle which the arm engaging that contact makes with the axis of the former. The ends of the arms 25 may be so shaped that they bridge the space between two adjacent contacts, thereby doubling the effective number of steps. When three arms are used they may be arranged so that they engage their contacts successively, so as to multiply the number of steps by three. In another construction, Fig. 4, a large number of lengths of thin low-resistance wire 29 are arranged parallel and close together in one panel. A circular moulding 30 of insulating material is then formed around them and has extension pieces 31 and a bridge 32 which receives the ends of the wires 29. These are cut off to expose their ends, against which the resistance windings 33 is clamped by screws 34. Contact arms 36 carried by a spindle 35 engage the wires 29. Alternatively a stack of such potentiometers may be used, one for each phase, with a common rotating spindle operating one contact arm for each potentiometer.

[Class 39 (i)] [Also in Group XI] A discharge device emitting both visible and ultra-violet light is associated with luminescent material for converting far ultra-violet in visible and near ultra-violet light, and is situated within a casing provided with a movable member comprising or co-operating with a light filter, whereby the lamp may be made to emit either near ultra-violet light only, or both visible and near ultra-violet light, as desired. The mercury-vapour lamp 1, Fig. 1, is enclosed in a reflector 10, with a front cover 12 of black glass 16, backed by two relatively rotatable polarizing layers 17, 18. The luminescent material may be on the lamp, reflector or front cover. If visible light is required, the cover may be removed, unless it bears the luminescent layer, when a separate port must be opened in the reflector. The filter may be formed into prisms to modify the shape of the beam. In Fig. 3, the obturator 26 is a rotatable semicylinder which allows either the filter 25 or a plain aperture 24 to be exposed to the lamp. The anode 5 and the heated cathode 7 are connected by a heater 9 for starting ; when running, a resistance is thrown in series with the discharge by a currentoperated relay.

Filed: 1976-07-01
Abstract: 1504171 Pie moulding apparatus BAYNFLAX Ltd 1 July 1976 [1 April 1975] 8669/75 Heading B5A In a pie moulding apparatus, foil pie containers 10, each carrying a measure of pastry, are manually fitted into recesses carried by a series of plates 7 slung between a pair of endless chains 1. The chains are continuously driven by a motor 12 through suitable belts and gearing 13, 14. The containers pass through a first work station 27 at which upper dies 35 cooperate with lower support cups 40 to form the pastry into cases, past a depositor 61 which drops filling into the case, past a station at which lids are supplied, and through a second work station 28 where the lids are crimped and trimmed between upper and lower shaping members. In both the working stations, the working members are carried by a carriage 29 which is lockable to the chains by air cylinder operated detents 59 so that the carriage may move with the chains during the operation of the working members. In addition, each carriage is engaged by an air cylinder 58 which aids its movement with the chains and which withdraws it to its starting position ready for a subsequent operation after the detents have been retracted. An overload preventing device is provided (see Fig. 6, not shown), the device comprising a sprocket spring biased against a belt driving the chains. In the event of overload the belt straightens and moves the sprocket which in turn withdraws a member from a normally closed switch to open it and stop the chain drive. The first working station comprises the carriage 29, which moves on rollers 30 along a guide track 3. The carriage carries a superstructure 32 including vertical guide rods. A lower carriage 57 upon which the support cups 40 are mounted is slidably mounted along the guide rods as in an upper carrier 33 from which the dies 35 are mounted by a diaphragm air cylinder 34. The lower carrier is connected by a pair of links 56 to one end of a pair of composite rocking members 44 centrally pivoted on trunnions 51 to the carriage. The other end of each rocking member is pivoted by a link 55 to the upper carrier and by a link 43 to one end of a beam 41 pivoted at 42 to a fixed upper plate of the superstructure. The other end of the beam is pivoted to the piston-rod 37 of an air cylinder 36 carried by the superstructure. In use, the air cylinders 36 are actuated to bring the dies and the cups almost to their working positions, the final closure movement of the dies being effected by the diaphragm air cylinder 34 alone.
